The Dragon Bravo Fire has burned more than 8,500 acres southeast of the Grand Canyon. The fire was sparked by lightning on July 4 and has destroyed dozens of structures on the North Rim, including the historic Grand Canyon Lodge.

The Grand Canyon's North Bravo Fire intensified on July 11, the day before Katy Rock Shop owner Jacob Proctor and his family arrived at the national park.

Gov. Katie Hobbs and Senators Mark Kelly and Ruben Gallego are calling for an independent investigation into how federal officials managed the Dragon Bravo Fire burning on the North Rim of Grand Canyon National Park.

A Grand Canyon water treatment facility located at the North Rim caught fire on Saturday, causing chlorine gas to be released into the air. Multiple closures are being enforced due to the incident.
